So there is 14 very very easy things to do in the first level right in deadpools apartment, I'll list them the order doesn't matter. Use the
to interact.
1. Watch TV
2. Practice Guitar
3. Pet the Dog
4. Go to the Book Shelf hit
5. Pump the Blow up Doll
6. Go on Computer
7. Look at Weapons
8. Eat Pizza
9. Drink beer from the fridge
10. Cook Pancakes on stove ( also an achievement)
11. Use the toilet
12. Wash Hands
13. Use the phone
14. Nap on the couch
There should be an achievement tracker after you do each thing to let you know how many you've done after the 14th the achievement will pop.
20 Gamerscore Plus the 10 Gamerscore for the cooking of the Pancakes.
Good Luck on this simple achievement enjoy!!!
UPDATE: Some players are saying you must keep chugging beers until Mr. Wade Wilson won't let you drink anymore and another player has stated that you MUST eat the full pizza, my play through I only ate a slice and it unlocked so I may vary for some strange reason. Again Good Luck & Happy Hunting !
